For what it's worth, here's my advice to the GOP Establishment: cut the tea partiers loose, and that includes those in your majority House conference.
You'll never again win the White House with the tea party base pulling you down and far to the right. Tea partiers are demographic poison for you; in their intoxicated, ideological flourishes they're happy to lose on what they bizarrely call principle, but you, the more electorally motivated GOPers, understand that politics and governance always come tinged with pragmatism and compromise. The two factions will forever be irreconcilable, an internal tension and, ultimately, a permanently losing proposition.
Cut the tea partiers loose. Cut them loose in the House and cut them in the Senate. Yes, you'll lose your House majority control for two years, but you'll gain a fundamental reorganization of political sanity that will pay immense rewards down the road.
And you'll have your party back--the real Republican Party of Lincoln and T.R. and Eisenhower, not this disgrace of a doctrinaire daycare center.
